โฆ Synopsis
Segregation analysis favors a gene additive on liability with a frequency of 0.022, which is nearly recessive on the penetrance scale. Less than one-eighth of DR3 and DR7 haplotypes carry a determinant for coeliac disease. There is significant excess of DR3/7 heterozygotes among patients, indicating that the determinants are qualitatively different in DR3 and DR7 haplotypes. Linkage to HLA is highly significant (maximum lod score = 10.9). Evidence for recombination of 8% in males is attributed to residual errors in the model. We suggest an approach to a more precise model.

Copper incorporation studies were performed on individuals from 58 pedigrees, comprising 140 sibships. As previously reported, there is considerable overlap between heterozygotes and normal homozygotes. Segregation analysis supports recessive inheritance of disease, with residual heritability for @C
Genetic epidemiology can contribute as greatly to the understanding of major chronic and degenerative diseases as classical genetics has to the understanding of inborn errors of metabolism and as classical epidemiology has to the understanding of diseases of environmental origin. Through increasing
